IMPROVEMENT IN TERRA-GOTTA ROOFING.

Specification forming part of Letters Patent No. 35,164, dated May 6, 1862-.

To all wiz/0771, it may concern:

Be it known that we, SAMUEL M. LOGAN and PHILO E. BAKER, of New Carlisle, Clark county, and State of Ohio, have invented certain new and useful Improvements in Covering Buildings with Terra-Cotta Tiling and we hereby declare that the following is a true and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The letter A in the annexed drawings represents a plan View of the tiling and caps as used on a roof. B in Fig. Qgives an end view of the same.

In the side view of the tile in Fig. 5 the letter E represents the opening at one end; I-I, the corresponding projection at the other. The dotted line designates the rim of the tile running lengthwise, and upon the rims, when the tiles are placed side by side on the roof, the caps c c are placed, they being constructed upon the same principle with the tiles, having a projection at one end, as shown by the letter f, Fig. 4, and an opening at the other, (represented by the letter g.)

In order to give a full understanding of the mode of covering a roof with our material, a description of a single tile is necessary.

Each tile is about four and a half inches in length and three and a half in width, consisting of what appears to be two strata or layers cemented together. The bottom layer, which rests on the plank sheeting with which the roof is first covered, is about the sixth of an inch in thickness, having a rim on each side running lengthwise of the tile, the rim being iive-eighths of an inch in height and of the same thickness as the lower stratum of the tile. The second layer begins three-quan ters of an inch below the upper end of the first, as shown by the letter P in Fig. 6, and extends the same distance below it at the other end, as represented by letter R, Fig. h'.

In making a roof with our tiles it .is necessary, in the first place, to cover the rafters with plank sheeting of uniform thickness to smooth surface, so that the tiles will fit snugly upon it. Then begin at the eaves and lay a tier of tiles from one end of the eaves to the other, fastening each in its place by a screw. The second tier is then laid on the lower end or lap (represented by letter R,) fitting in the open space P and screwed in that position. Successive tiers are laid on in a similar manner until the roof is covered. The joints or seams running between the several rows of tiles from the eaves to the peak of the roof are then covered with the caps, the ends of which lap each other in the same manner as the tiles and secured in position by screws. The points of interjunction in the caps are filled with a cement of eggs and yellow ocher to render them impervious to water.

Having thus accurately described our invention, what we claim, and wishl to secure by Letters Patent, is-

1. The use of the caps a a for covering the joints, in the manner herein set forth and described.

2. The caps, in combination with the laps b b, in the manner and for the purpose herein set forth and described.
